Baokun Li 63ec0c26b6 tmpfs: preserve SB_I_VERSION on remount
Now tmpfs enables i_version by default and tmpfs does not modify it.  But
SB_I_VERSION can also be modified via sb_flags, and reconfigure_super()
always overwrites the existing flags with the latest ones.  This means
that if tmpfs is remounted without specifying iversion, the default
i_version will be unexpectedly disabled.

To ensure iversion remains enabled, SB_I_VERSION is now always set for
fc->sb_flags in shmem_init_fs_context(), instead of for sb->s_flags in
shmem_fill_super().
